HYDRAULIC AN D AUTOMATIC WASTE VALVE FOR VESSELS.

Application led January 7, 1925. Serial No. 978.

This invention relates, generally, to waste valves for liquid containing vessels` but has particular relation to that type of valves employed in connection with bath tubs and the like, and embodies improvements on or over the structure or construction disclosed in Letters Patent No. 1,049,828, granted to me on the 7th day of January, 1913, for improvements in hydraulic and automatic waste-valves for vessels.

The present invention has, as one of the main objects thereof, the provision of a waste-valve, more particularly for bath tubs, but not restricted thereto, which shall be of such construction, arrangement and combination of its parts as to conform to the new order or style in bath tubs, known as the built-in type, in which the fixtures of the tubs are concealed, and so as to comply with the law and regulations ot the sanitary boards of many cities, which require that traps or water seals in connection with the waste or drain pipes of bath tubs, as shown in Fig. 1 of the drawings, of my above mentioned patent, shall not be employed.

Another and important object of my present invention is the provision of means whereby, when the devices are employed in connection with bath tubs of the built-in and iXture-concealed type, certain parts thereof, those most likely to require clean-- ing, adjustment and repairs, may be readily removed from their concealed or operative positions and quickly replaced, without interference with the closure for the fixtures.

" A further object is to furnish a waste valve for vessels that will act or waste automatically at a given pressureof liquid, and which shall have manually operable means for discharging. all or any desired amount of liquid from the vessel.

Other objects and advantages of the invention will be disclosed in the following del'scription and explanation, which will be more readily understood when read in conjunction with the accom anying drawings, in which embodiments o the invention are illustrated, it\being understood that modifications and changes may be resorted to without a departure from the invention, so long as they fall within the sco e of the appended claims forming a part ereof.

Corresponding numerals of reference refer to like parts throughout the dii'erent views of the drawings.

Referring now to Figs. 1 to 5 inclusive of the drawings, the reference numeral 10 desi nates a portion of a bath tub of the uiltfin type, the line of the closure for concealing the -xtures thereof being indicated at 11 in Fig. 1 of the drawing. The tub 10 is provided in its lower` surface .near its upwardly extended end wall adjacent the line 11 of the closure for the fxtpres with a drain or waste opening 12 and near the upper portion of said wall with an overflow opening 13 both of which openings are by preference circular in shape. The waste o ning 12 has fitted therein so as to be abut Hush at its upper end with the upper surface of the bottom of the tub a short nozzle 14 which is by preference externally screwthreaded to engage the upper end of the L-coupling 15 between which and the bottom of the tub is located suitable packing 16-to prevent leakage. lThe nozzle or meinber 14 is provided internally with a transversely disposed apertured bar 17 for engagement with the lower end of a screw 18 employed to detachably secure to the mouth of the nozzle or member 14 a perforated is provided centrally with for engagement with the inner ends an opening ffor the said screw.' The over'- iiow opening 13 of the tub has fitted thereto in any suitable manner on the outside of the upwardly extended end wall of the tub an L-coupling 20, which coupling has on its inner surface near its end adjacent the opening 13 a pair of apertured and diametrically disposed lugs 21, see Figs. 2 and 5, ot screws 22 which are employed for securing aperforated bearing member 23 to the upright end wall of the tub over said overiiow openin This bearing member 23 has a central y disposed hub 24 in which is located a rotary shaft 25 which is provided on its end within the coupling 20 with a crank 26 and on its other end with a handle 27 for use in manually operating the valve when so desired. The screws 22 are extended through suitable openings in the member 23 and as will be readily understood by reference to Figs. 2 and 5 of the drawings, engage the lugs, 21 on the coupling 20 so as to securely clam the members 2() and 23 lon the outer and inner surfaces respectively of the upright end wall of the tub around the opening 13 therein, or should it be desired, against packing rings 28 and 29 located at the peripheries of said members around said opening.

Screwed or otherwise tted at one of its ends-into the lower end of the cou ling 15 is a horizontally disposed waste tu e or pipe 30 to the other end of which the valve casing of the device is connected. This valve casing is, when viewed sidewise, substantially of the shape of a T-sha edcoupling;

that is, .it is provided with t ree ways or=V atubular portions which communicate with one anot ier inwardly of their outer ends. One of these tubular portions, which may be termed the inlet of the valve, indicated b the numeral 31, is connected to the waste pipe or tube 30 by means of a coupling 32, while another 33 of these tubular ortions or ways which is located opposite t e tubu- -is clearly shown in lar portion or way 31, is connected to a discharge pipe 34 leadingv to any suitable point of discharge, and may be termed the outlet ortion or way. The ortions 31 and 33, as iierent views of the drawings, are located substantially in a horizontal plane but with the lower portion of the part 33 disposed at a. somewhat lower level than the lower portion of the part 31 or inlet. Between the tubular portions 31 and 33 the valve casingis'provided with a vertically disposed tubular portion or way Sti-which has communication through a pipe 36 with ythe L-coupling 20 of the overflow opening of the bath tub as' will be readily understood by reference to 1, in which view it will be seen that the ower portion of the pipe 36 is connected to the overflow way or tubular portion 35 by means of a coupling 37 and that the discharge pi c 34 is connected to the outlet way or tu ular portion 33 by means of a coupling 38 of a well known construction and in the usual manner.

The valve casing is provided between its tubular portion or way 35' and the tubular portion or way 31 with a vertical partition 39 which terminates or is provided with a horizontally disposed valve seat 40 located between the partition 39 and the lower portion of the outlet way or portion 33 of the valve casing in such a way that its lower surface will occupy a plane slightly above the inner surfaces of the lower parts of the Ways or ortions 31 and 33 of the valve casing, whic casing is provided below the partition 39 and said valve seat with a pocket having sloping walls. The opening or valve seat 40 is located below the lower end of the pipe 36 so that their axes will be in true alignment.

Located within the valve casing above the seat 40 thereof to co-operate with said seat is a spherical shaped valve 42 which is provided at its upper portion with a vertical extension 43 united to the lower portion of a guide member 44 which is by preference cylindrical in shape or of a shape to correspond with the pipe or conduit 36 in the lower portion of which it is located for vertical movement. This guide member 44 is by preerence hollow and has apertures in its upper and lower ends as is clearly shown in Figs. 1, 2 and 4 of the drawings to per/- mit of the free passage of water. The upper end of the guide plunger 44 is provided with an upright extension 45 to which is loosely connected the lower end of a iexible connection 46 such as a chain, the other end of which is loosely connected to the crank 26 on the crank rod or shaft 25 in such a way that by turning the handle 27 on said rod in the proper direction, the valve may be raised from its seat, in which operation it is manifest that the guide plunger 44 will be guided in its movement by the tube 36 which acts in the capacity of a guide for said plunger and the valve as well as a conduit for the overiiow water from the tub.

From the foregoineand by reference to the drawings, it will readily understood and clearly seen that by-my improvements l have provided a waste valve mechanism in f es anism at f exposed fixture or for the valve and its guidev at its lower end ployed in the first which the valve will be automatically operated so as to permit water in excess of a predetermined amount to be discharged from the tub or vessel, for it will be understood that a valve with its vertical extension, and guide plunger, of a weight suilicient be overcome by a. predetermined amount ol water pressure can be selected and connected to the flexible connection 46, whereby it may be positively or manual-ly operatedas above stated. It is further apparent that by my .improvements I have provided a structure in which water traps or seals connected with-the drain pipes of bath tubs or the like, is eliminated as in the operation of the device, but a small quantity of water, insutiicient to seal the valve seat, will accumulate in the pocket 41 below the valve. By removing the screws 22 from engagement with the lugs 21 on the L-coupling 20, it is apparent the bearing member 23 carrying the crank rod 25, connection 46, the valve and its guide plunger can be readily removed, thus permitting said parts to be cleansed or repaired and also allowing the valve casing and tube 36 to be cleansed. By removing the strainer 19 it is obvious that a suitable instrument may be inserted through the nozzle 14, drain pipe 33, into the pocket 41 for the purpose of" removing sediment and the like therefrom.

In Figs. 6 to 8 inclusive is shown a modification in the construction of the'valve mechwhich is more particularly intended or use in connection with bath tubs of the heretofore commonly modification the valve casing 1s of the same construction as that shown in Figs. 1 to 3 inclusive and above described,.with the exception that the upper end of the vertical tubular portion .or way is equip ed with an orillced cap 48 screwthreaded t erein, said ca having a small guide tube 49 for the flexible connectionv 46 plunger located in the opening of the cap and extended upwardly but terminating below the handled crank rod used for manually operating the valve.

his small pipe, besides serving as a guide for the connection 46, also acts as a receptacle for water should the device be manually, operated the water would rush into the valve casing and by gravity force the water would rise in said pipe to a given point and then recede. In this modified form of the device a bearing member 23 for used type. In this 'the crank shaft 25 is employed to cover an opening 50 in the upper portion of an end wall of atub provided for the reception of said bearing member, and this bearing member dill'ers in construction from the one em- 1n that it is not intended that the opening 50 shall be employed as an overflow open- `said bearing member or rather on vessel, a valve seated in above described structure l ing. The bearing member 23 is secured to the end wall of the tub 10 by means of screws 51 inserted through suitable openings in the member 23a and each engaging a suitable opening in a clampinv plate 52 located on the surface of the tub opposilte a Pa ing ring 53 interposed between said plates` and the outer surface of the tub to prevent leakage. i i
